In Unity, what is the effect of setting the Indirect Multiplier on decorative lights to 0?

Setting the Indirect Multiplier on decorative lights to 0 effectively eliminates their contribution to indirect lighting in the scene. The indirect lighting is created when light bounces off surfaces and contributes to the overall illumination of the environment. By reducing the indirect multiplier to 0, those specific lights will no longer affect the indirect light calculated by Unity, meaning they won't add any extra light to the surrounding area indirectly. This is particularly useful for achieving a specific artistic effect or when fine-tuning lighting to achieve the desired atmosphere within a game or application.

The options that involve increasing memory usage, enhancing overall brightness, or enabling colored shadows do not accurately reflect the function of the Indirect Multiplier. The Indirect Multiplier is specifically tied to how lights contribute to indirect lighting rather than affecting memory, brightness, or shadow color.
